Description
Product Description
The IC695ACC302 is an advanced auxiliary battery module for PACSystems RX3i and RX7i CPUs, providing extended backup for volatile RAM memory. Its integrated smart monitoring circuitry allows the CPU to detect low battery conditions early, preventing unexpected data loss. Designed for long-term reliability, this module replaces standard coin-cell or lithium backup batteries and connects directly to the CPU with the included enabling adapter cable.
